Disclosed is a system for generating alerts communicated to emergency responders and/or contacts indicating a location of an incident. The system comprises a housing, one or more light sources, and a computing processor. A switch is located in the housing and configured to be accessible to a user. When the switch is actuated by a user indicating an incident, the processor provides power to the at least one light source to output light from the housing thereby indicating the location of the system. The system may also control a speaker to output an audible signal and a transmitter to transmit an emergency signal with location information to a device of an emergency responder and/or an emergency contact. The present invention may also be embodied in a software application that is implemented on a mobile device to thereby leverage the components of the mobile device to send alerts.

A system includes a depression, a liquid, a gas inlet, an aspiration system, an aspirator, and a gas detector. The depression is formed into a floor. The liquid is disposed within the depression. An unoccupied space is delineated by a surface level of the liquid and a depth of the depression in the floor. The gas inlet is located within the unoccupied space in the depression. the aspiration system is connected to the gas inlet by a tube and located outside of the depression. The aspirator is located within the aspiration system and configured to create a vacuum to draw a gas mixture from the unoccupied space into the aspiration system using the gas inlet and the tube. The gas detector is located within the aspiration system and is configured to detect a specific gas.

An electronic relative directional indicator includes a microcontroller in electronic communication with an electronic compass, an electronic motion-detecting module and at least one light source that is controllably illuminable A battery life of the electronic relative directional indicator is managed by monitoring the electronic motion-detecting module for motion within pre-defined time periods and reducing power to electronic components accordingly. The electronic relative directional indicator can be placed on the face shield portion of a self-contained breathing apparatus face mask to provide a constant source of orientation for firefighters in reduced- or zero-visibility environments.

A protective system for a cast saw includes a voltage source and a processor coupled to the voltage source. The processor is configured to apply a voltage to a saw blade of a cast saw. The processor is also configured to receive a voltage reading taken across a conductive layer that is at least partially embedded in a cast. The processor is also configured to determine whether the received voltage reading exceeds a threshold voltage. Responsive to a determination that the received voltage exceeds the threshold voltage, the processor is further configured to activate an alarm to warn a user of the cast saw that the saw blade is in contact with the conductive layer.

Systems and methods for directing an alert to responders are provided. Upon activation of an alert application on a user device, an options screen is displayed to a user. The user can select a report option, and a screen is displayed for the user to enter information into one or more required and optional fields regarding a threat or a risk event. Once the system determines that the required fields have been filled, the system automatically composes a customized alert message based on the received information, automatically determines appropriate responders to notify. The customized alert message is transmitted to the determined responders, and acknowledgement messages are received from the responders.

A device for illumination and fire safety in a room includes a housing, one or more light emitting devices, one or more fire safety components, and a controller. The one or more light emitting devices are coupled to the housing and configured to provide ambient lighting for the room during a normal mode of operation. The one or more fire safety components are coupled to the housing and configured to notify occupants of the room of a fire during an alarm mode of operation. The controller is configured to transition from the normal mode of operation into the alarm mode of operation in response to detecting the fire. The device may include facilities for remote self-testing which may include one or more of a light detector, a sound detector, and a smoke emission system. The device may perform the self-test in a test mode.

A device for providing an alert for an event, the device includes a microphone to receive ambient sounds external to the device and a processor and memory to analyze the ambient sounds received by the microphone wherein, based on a priority level assigned to a type of audiovisual media being played on the device, the processor selectively activates a pass thru mode of the device in response to determining that one of the ambient sounds matches a trigger sound, the pass thru mode providing the alert for the event by interrupting the audiovisual media being played on the device such that the ambient sounds can be heard by the user.
